THe actuators' design and manufacture are aimed at the use of ball vaklves closing with DN 700, DN 1000, DN 1400: quater-turn electric actuators having nominal torque 210 kNm close and open the ball valves (rotation angle 90˚) within 11 minutes.
The quater-turn electric actuators were desined and produced to close the ball valves having DN 32, they have nominal torque 10 Nm and close/open the ball valves (rotation angle 90˚)within 8 seconds.
The oil-filled gears of the planetary-excentric type are designed and produced for using them along with the multi-turn electric actuators with the purpose of making single-turn electric actuators. they have:
some maximum torques 8, 16, 32, 64 kNm; transfer values 48, 70; coefficient of efficiency is 0,8, automatic indicator of the output shaft position.
